16 Claims. 1

This invention relates to automatic bowling pin setting machinesand,more particularly; to a control for setting and starting an automaticpin setting machine for a predetermined number of players forone gameandautomatically shutting'it off when the game has-been completed;

When an automatic pin setting machine iseinployed-on a bowling" alley}some provisiorrhas to be 'made to see that players receive the number offrames to which they areentitl'ed", after which the machine-is shutoff.If this isdone' by attend"- ants, it is costly which. of course, adds tothe cost of the game. By using my invention, such close supervision isnot" necessary because the machine is controlled automatically.

In the game" of bowling the players on two opposing teams usuallyalternate for each frame between two adjoining alleys; The number ofplayersona teammay also vary from game to game and the number of ballseach player is entitled to receive in any game varies depending upon hisplay in the last frame of the game. My invention not only provides forthese various factors, but is also tied in with the control'system of anautomatic pin setting machine so that it will start v.the.machine,..allow-each player the number of balls to which he 'isentitled, then clear the alley, and set up ten new pins and then shutoffthe machine:

My'inventionis also adapted for use either as a coinoperateddevicefwhereby players may depositcoins directly in the coin box to setthe machinefor a fixedanumber of players or as acontrolwhich can bemanually set by the manager of thetbowling'. alley.

An advantage of my gamercontrolisthat it mayfbe used with'automaticpimsetting and ball return 'machinesr: where! two opposing teams ofplayers :play on two separate :alleysiand. alternate between theitwoalleys'forieach succeeding frame.

Anotherradvantage ofv myiinvention: is that'it operates equallywell'where the teams do not alternate between the alleysbut:instead-play all their frames on the same alley.

Another advantage of mycontrol device is that it starts the pinsettingmachine and counts the number of framesplaycd by the players on a-teamand. inthettenth frame,-:automaticallyallows each player: of the teamwho makes astrike to throw two extra balls and allows eachplayer of theteam who makes a spare in the tenth frame to throw one additional ball.After all the play-- are have. thrown all the balls to which they areentitled, my device automatically causes the machine to clear the alleyand to set up ten new pins, and then it shuts off the machine.

Another advantage of my device is that, if the playersteps over thefouiline, he is automatically notified thathe has'transgressed beyond thefoul line'and,"if he steps back of the foul line without throwing theball, the foul warning will be automatically cancelled'after apredetermined period of time has'elapsed (forexample ten seconds). If,on the other. hand; the player/has transgressed beyond the'foul line andhas thrown the ball, the foul'impulse "will not 'be cancelled and thefoul will be registered againstthe player.

Another advantage of my device is that it will be unnecessary to haveattendants present to oversee and supervise the" bowling of variousteams to see that they do not play-moreframes than they areentitled't'o.

Another advanta'geof my invention is that it causes the bowling machineto'operate and clear the'alley and set ten new pins-eachutime a playerhas thrown the last ball to which he is entitled in the game.

A further object is to provide apparatus-for accomplishing the foregoingobjectives which will be reliable and accurate in operation.

Another advantageof'my invention is that it allows additional playerstoentera gameafter it has started at anytime up to the tenth frame.

Other objects and features of the invention will appear as thedescription of. the particular physical embodimentselected'to illustratethe invention progresses.

I. PRINCIPLES'OF THE GAME-0F BOWLING My invention is designed tomeet-the conditions of a game of bowling. In agame of ten pins; a gamecustomarily consists of ten framesand each player is allowed to throwtwo balls in each frame.

When a player knocks 'downall ten pins with the first ball it is knownas 'a-strike and when he succeeds in knocking'down all pins with twoballs in a frame" it is knownfas a spare.

In the tenth frame it is customary to allow a player to throw twoadditional balls when he makes'a strike and one additional ball when hemakes a spare. Accordingly my device is designed to allow each playersuch additional balls to which he is entitled before shutting oif theautomatic pin setting machine.

While the foregoing description briefly outlines the principal featuresof the game .of tenpins, various modifications of these features may bemade, such as changing the number of frames for a game, changing thenumber of balls allowed, allowing different numbers of extra balls to bethrown in the event a spare or strike is made, changing the number ofpins, etc. Whenever such changes in the rules are made, correspondingchanges may be made in the apparatus hereinafter described to correspondto any such changes in the rules. My invention is, therefore,

equally adapted for use with a game of duckpins, candlepins, kingpins orany other variation of the game of bowling.

II. AUTOMATIC MECHANISM FOR SPOTTING AND RESPOTTING PINS Various deviceshave been developed to spot and respot bowling pins by automaticapparatus instead of by hand. My invention is adapted for use with suchautomatic pin spotters. My copending application, S. N. 627,605, filedNovember 9, 1945, which has now matured into U. S. Patent 2,559,274granted July 3, 1951, shows one type of automatic pin spotting machinewith which my invention can be advantageously employed.

The mechanical apparatus shown in that application employs a platformwhich is adapted to move toward and away from the bed of a bowling alleyto either spot or respot bowling pins on a bowling alley.

Mechanical means are provided for returning the bowling ball to theplayer along a runway and for elevating the fallen pins and placing themin a magazine from which they are eventually delivered to the spottingplatform.

It should be understood that, while I have referred to the type ofmechanical apparatus shown and described in my former copendingapplication, Serial No. 627,605, filed November 9, 1945, now U. S.Patent 2,559,274, other mechanical structures can also be advantageouslyemployed with my game control.

III. SEQUENCE CONTROL FOR AUTOMATIC PIN SPOTTING AND RESPOTTING MACHINESFor purposes of illustration, I will show how my game control can beemployed with the sequence control shown in my copending application,referred to abve,'to operate a pin spotting machine in a certainpredetermined sequence, depending upon whether the first or second ballhas been thrown or upon whether a strike, a spare or a foul has beenmade.

For example, if a strike is made, the bowling pin setting mechanism willbe put through a series of operations which will remove all fallen pinsand reset a new set of pins on the bowling alley. If a foul is made onthe first ball, all of the pins will similarly be removed and a new setof pins will be placed on the bowling alley. If a first ball has beenthrown and there is no strike or foul, the machine will remove any pinsthat have fallen and will return the bowling ball to the player so thathe can throw'his second ball. For further details as to how the sequencecontrol operates, reference may be made to my 'copending application,Serial No. 627,605.

My game control is constructed to operate satisfactorily regardless ofwhether the players of two opposing teams use two alleys or one alle Itis also adapted to operate equally well in the case where two alleys areemployed and the players of each team alternate between alleys inplaying successive frames or where the players on each team play alltheir frames on the same alley.

In any of the cases mentioned after each player has played ten framesand has received all the extra balls to which he is entitled as a resultof making a strike or a spare in the tenth frame, my control actuatesthe machine to clear the alley and set up a new setof pins for the nextplayer. When all the players have completed ten frames each, togetherwith such extra balls to which they are entitled, my control causes thealley to be cleared and a new set of pins to be set up, and it thenshuts off the machine.

My frame counting and bowling machine control apparatus may be setmanually by the manager of a bowling alley for a predetermined number offrames for a team and, after it has allowed each player any additionalballs to which he is entitled in the tenth frame, it will automaticallyshut off the machine. My bowling machine control apparatus may also beused with a coin operated mechanism so that attendants and supervisorsfor a game of bowling may be dispensed with and each team can proceed toplay immediately by inserting the required number of coins into asuitable coin control box.

1. Description-coin boa:

In Fig. 1, I have shown one type of coin box or receiver which can beused with my bowling machine control apparatus. This coin receiverconsists of a housing In having an end plate l2 connected thereto at oneend. 'Secured to the end plate I2 is a plate l4 having circular hole Itin which a coin wheel I8 is mounted for rotary movement. A cover plate20, having a coin insert opening 22 formed therein, is secured to thebox Ill by means of suitable screws 24. Fixedly secured to plate I4 arefour supporting studs 26 (only two shown in Fig. 1) which are heldsecurely by means of screws 28. Secured to the opposite ends of the foursupporting studs 26, by means of nuts 32, is a supporting plate 30.

The opening 22 in plate 20 is not located directly over opening 50 incoin wheel I8, but each opening 50 has a shelf 50a which extendsunderneath opening 22. When the coin is inserted, it must be slidunderneath plate 20 into opening 50. This arrangement prevents tamperingthat might be possible if opening 22 were located directly over opening50.

A shaft 34 passes through and is rotatably mounted in a suitable holeformed in the (cover plate 23. Part of the shaft 34 has a square portion35, on which is fixedly mounted the coin 328m, 3281) and 3281:. (Fig.8). Contact 3281) is in series with spare lamp relay 316 and contact323a is in series with the ratchet relay 359. Relays 319 and 359 arecontrolled by the two sides of electrical control cam 332. The normallyopen contact 328d acts as lock-in contact for relay 328 and is connectedin multiple with the ten 3260 contacts of lamp relays 323. The normallyclosed contact 328m is connected in series with the strike lamp relay363. Normally closed contact 328a is connected in series with an addedthird contact 3 In of cam 3M (Fig. 8).

A normally closed contact 366d was added to off center relay 355 (Fig.8) for the purpose of energizing no pin relay 323 from cam 332 underspecial circumstances arising on the last ball which will be more fullyexplained later.

Normally closed contact 36Ib and normally open contact 36 la were addedto the table turning and pin distributing actuating cam clutch relay36I.

A normally closed contact M29 was added to the relay H2. Normally open,contact 4I6f was added to relay 4 I 6.

. A new normally open contact 3981) was substituted for M2?) in the lockin circuit of relay M2 to cancel a foul if no foul was in fact committedby the player. This will be more fully explained later.

A motor control unit MC, Fig. 8, was added through which the machine isstarted and stopped.

It will, therefore, be evident, as indicated above, that the circuitdiagram shown in Fig. 8, except for the few changes just mentioned, issubstantially the same as the circuit wiring diagram shown in Fig. 4 ofmy former application S. N. 627,605.

The wiring diagram shown in Fig. 4 of my former application S. N.627,605 and in Fig, 8 of this application is what may be referred to asa sequence control for a bowling machine. Its operation may be brieflyoutlined as follows:

If a strike or a foul is made on the first ball, it puts the machinethrough a series 01 operations which will clear the alley and set up anew set of pins and return the bowling ball to the player. On the secondball, the machine will likewise be put through a, series of operationswhich will clear the alley and set up a new set of pins regardless ofwhether it is a partial score, spare or foul. If a player fails to knockdown all ten pins on the first ball, the machine will be put through asequence of operations which will cause the pins that remain standing tobe gripped and elevated above the alley while the fallen pins and ballare removed from the alley and, thereafter, the standing pins will bereplaced on the alley to enable the player to throw his second ball.

As was described in my copending application, various safety devices areprovided which will stop the machine from operatin under certainspecified conditions, such as pins being too far off center or wherethere is an insufiicient number of pins in the spotter cups. Since theoperation of the sequence control is already adequately described in mycopending application, S. N. 627,605, now U. S. Patent 2,559,274, it isnot necessary to go into further detail on its operation in thisapplication. I will instead describe in detail how the circuit diagramshown in Fig. 9 ties in with the sequence control and how it operates tostart the machine, count frames for a number of players, cancel or makefouls eflfective, how it causes the alley to be cleared in differentstages of the game and puts a new set of pins on the alley, and how itshuts 01f the machine at the completion of the game.

3. Description and operation of the game control for an automaticbowling machine advances the wiper arm W of each bank on step each timethe operating solenoid is deenergized.

Stepper switches S5 and S6 (Fig. 9) are provided with ratchet wheels I II and I I3 respectively. The ratchet wheels I I I and H3 and the wiperblades W are fixedly mounted on shaft H5 and II? of their respectivestepper switches S5 and S6.

The ratchet wheels I I I and I I3 are rotated one step at a time bypawls II9 and IZI respectively which are held in engagement with theratchet Wheels III and H3 by means of springs I23 and I25. The leverarms I2? and I29, on which the pawls H9 and I2I are mounted, have adownward force exerted thereon by means of springs I3I and I33, Theplungers of solenoids I35 and I31 are connected to the lever arms I21and I29 and, when energized, cause the lever arms to be elevated. Whenthe solenoids I35 and I3! are deenergized, the lever arms I21 and I 29due to the downward pulling action of springs I3I and I33, cause thepawls II9 and I2I to engage with the teeth of their respective ratchetwheels and advance the Wheels one notch.

since the ratchet wheels I I I and I I3 are fixedly mounted on the sameshafts H5 and III as the respective wiper blades W of each stepperswitch S5 and S6, the wiper blades W are advanced one contact point inthe direction indicated by the arrows whenever their respectivesolenoids are energized and deenergized. It should be noted that theplunger arms of solenoids I35 and I3! break electrical contacts I39 andMI each time they are energized. This principle of breaking a contact bythe plunger arms of solenoids I35 and I3! may be compared to whathappens in the ringing of an electrical bell. ever, the number ofcontact breaks made by the plungers of solenoids I35 and I31 is verycarefully controlled as wil1 be brought out herein.

(a) COUNT OF FIRST 9 FRAMES FOR EACH PLAYER OF A TEAM Let us assume, forpurposes of illustration, that there are two teams, each team consistingof three players, and that these teams will play on two alleys which areequipped with coin operated game control apparatus.

In accordance with the usual practice, the players of one team willfirst play one frame on one alley and will then change alleys with theplayers of the opposing team and play the second on the other alley. Theplayers of each team thus continu alternating between alleys for eachsucceeding frame until all ten frames have been completed. My controlapparatus used on each alley will function correctly when this practiceis followed, as well as in the case where the players In'this case, how-7 of each team play all ten frames on the same alley withoutalternating.

Coins corresponding to the number of players on a team are insertedthrough the insert opening 22 of the coin control box for each alley.Since the game control apparatus of each alley is independent of that onthe adjoining alley, it will be sufficient to merely describe how one ofthese apparatus will operate since each operates in a similar manner.

When one coin has been inserted into the slotted opening 22, th contactsegment 52 of the selector switch 55 (Figs. 6 and 9) can then beadvanced one contact by turning knob at and the contact segment 52 willthen be contact with the cotact points 2, it, t, 5, iand I. Sincecontact :7 is energized through wire M3, current will also be applied tocontacts .2, t, t, and S of the selector switch 5 The motor control MSis energized through wire hi5 from contact 6 to start the machine. Whenthe shaft 3-! has been rotated one notch as just described, it willcause the high part of earn 553 to close the Ii Iicroswitch M (Figs. 3and 9) to thereby apply power to the entire sequence control throughwire it! (Figs. 8 and 9). Contacts 2, i, and ii of the selector switchEd apply current through wir lei, 253;, and i5% to contact points 2, and5 of bank I of step-per switch. S3 and contact points i, 2, 3, and :i ofbank II of stepper switch as well as contact points I? to 23 of bank IVof step-per switch S35.

If three coins are deposited and segment 52 of the selector switch isrotated three steps, power will be applied to contact points 5, 5, I, 3and t of the selector switch Fewer will then be transferred from contactpoints and 5 of the selector switch 5 3 through wires and tee tocontacts id to of bank IV of the stepper switch to contact points #3 andof bank I and contact points 3 and t of bani: II of stepper switch S5.

When the three coins have been deposited in the coin insert the shaftrotated in the manner described, the stopper magnet E35 will beconnected across the solenoid. 22 which operates the magnetic framecounter through wire lEiI (Fig. 8), normally open contact wire E59,normally closed contact ifila of switch-over relay ti and through wirelets. These connections will cause the wiper arms W of stepper switch S5to advance one step for each frame played on the alley in the sam manneras the frame counter is advanced one digit for each frame by thesolenoid as described in my U. S. Patent 2,559,274. This means that incase a foul is made on the first ball, relay did is energized therebyopening normally closed contact use, which opens the power circuit tosolenoid 322 as well as to stepper magnet 8-5. This prevents stepperswitch S5 from advancing on this first bail, even though a new set often pins is deposited on the alley, but it will advance on the secondball of this frame when another set of ten pins is placed on the alley.

Starting in zero position, after the first player has completed playingone frame, the stepper switch S5 will be energized in the manner do"scribed so that the wiper blades W will have advanced to step or contactpoint No. 1 on banks I, II, III IV. During this operation relay Edi andframe counting magnet 322 are simultaneously energized. Therefore,contact ie is closed and magnet I35 of stepper switch 6-5 is alsosimultaneously energized. When nine frames have been played on thealley, the wiper blades will id have advanced to position No 9 on eachof the four banks of the stepper switch S5.

Steps 9 to 24 of bank 11 of stepper switch S5 are energized through wireE55, contact i690, wire it? and wire it? from the cam actuated switch M(Fig. 9). The solenoid 535 of stepper switch S5 is connected to wiperarm W ofbank II through its interrupter contact I39. Since the points Qto 2d of bank II of stepper switch S5 are all energized, the wiper W ofbank IIuWili continue to energize IE5 at each of these contact points.As a result, the wiper W of bank II; being connected in series withsolenoid l35'wil1 cause the switch S5 to spin until it isback. to zeroposition. During this spinning operation relay 361 is not energized,contact sew is open and magnetic frame counter 226 is prevented fromadvancing with each step of stepper switch S5 from position 9 toposition 24 and back to zero. During this same spinning operation, whilethe wiper of bank IV passes contacts it to 23, normally-open contactlfiic prevents power from being fed from the wiper of bank II to thewiper of bank IV of stepper switch S5, through contacts ii! to 23 to thecontacts 25 of bank I and I4 of bank II or stepper switch S5.

Step 2d of bank III of stepper switch S5 is also connected to powerthrough wire- III (Fig. 9) from the cam controlled switch M; while thewiper W of bank III of stepper switch S5 is connected through wire Itothe solenoid E3! of stepper switch so through its interrupter contacti i! (Fig. 9). When the wiper blades W of stepper switch S5 are causedto spin in the manner just mentioned, the wiper blade W ;of.-bank IIIpasses the contact point 24. When it passes this point, it causes thestepper switch S5 to be energized and advance the wiper arms of stepperswitch S5 one step to position No. 1.

Upon the completion of the next. frame on this alley, the stepper switchS5 will again be energized by the same means which energize the solenoid322 actuating the frame counte1v420 (Figs. 3 and 9); This causes wiperblades W of stepper switch S5 to again advance to position No. 1.

The frame, following the frame just mentioned causes S5 to again advancethe wiper blades W one step in thesame manner. This process continuesuntil the wiper blades W of S5 reach the ninth point whereupon theyagain automatically spin back to zero position in the manner justdescribed. When the wiper,,b1ade W of bank III of stepper switch S5.passes contact point 24, it causes S6 to be again energized through wireM35 as previously described. This results in the wiper arms W of stepperswitch S6 being advanced to step or contact point 2.

The wiper contactarms W of stepperswitch S5 are then advanced again onestep to position No. 1 through the same means that actuates the solenoid322 which operates the frame counter 220. This process continues untilthe wiper arms W of so have been spun through points e -1 24 of bank IIof stepper switch S5 three times.

The third time the wiper blades W of stepper switch S5 pass contact '24of bank III, it energizes stepper switch S6 thus advancing thewiper armsW of stepper switch S5 toposition No. 3. Since position No. 3 of bank IIof stepper switch S5 is energized through wire I53 from contact 4 ofselector switch 54, it causes switch-overrelay it! through wire H9, andcoin :wheel-lock-in electromagnet S'l through wire 18L to also be'- comeenergized. When the lock-in mag-net S1 becomes energized, it pulls inthe arm I08 looking the ratchet wheel 38 (Figs. 1 and 9) against furthermovement. From this point on, therefore, no more coins can be used toenable the knob 40 to be turned to allow additional players to enter thegame. It will be noted that prior to this time, additional players couldenter the game by merely inserting an additional coin into the coininsert and turning the knob 40 one notch. Such additional players wouldreceive the same number of frames and balls as the other players alreadyin the game.

Since switch-over relay IEI becomes energized, normally closed contactI6Ic is opened thereby disconnecting contact points 9 to 24 of bank IIof stepper switch S from power. Normally open contact IBId, on the otherhand, is closed causing contact points I to 8 of bank II of switch S5through wire I83, and contact points II, I4, I7, 20 and 23 of bank I ofstepper switch S5 through wire III, to be connected to power.

Since contact points I to 8 of bank II of stepper switch S5 are nowconnected to power, this will cause the wiper blade W, which isconnected to the solenoid I35 of stepper switch S5, to spin to contactpoint 9.

The energization of switch-over relay I6I also causes the normallyclosed contact I6Ia to be opened and, from this point on, stepper magnetI35 will be energized through the contact I6Ib, through contact 34Ih ofelectrical control cam 34I (Fig. 8) and also through contact 35Ib of thetable turning and pin distributing actuating cam clutch relay 35I.

I have just described how my control counts a total of 27 frames for ateam of three players (9 frames for each player). If four players wereon each team, my control mechanism would have counted 36 frames insteadof 27 frames before the switch-over relay I BI and the coin wheel lock57 were actuated. On the other hand, if only two players were on eachteam, the switch-over relay IBI would be actuated after 18 frames hadbeen counted (9 frames for each player). Similarly, if there were onlyone player on each team, the switch-over relay I6I would be actuatedafter 9 frames had been counted. It will, therefore, be evident that thesetting of the selector switch 54 controls, through bank II of stepperswitch S5 and the switch-over relay I6I (Fig. 9), the number of timeswiper arm W of bank II of stepper switch S5 will be permitted to spinpast the points 9 to 24.

' After each player on the team has played 9 frames or a total of 27frames for the team, my control checks each player in his tenth frame todetermine whether or not he has made either a spare or a strike and,therefore, would be entitled to one or two additional ballsrespectively.

(12) FIRST BALL OF THE FIRST PLAYER IN th FRAME IS A NORMAL BALL,STRIKE, OR FOUL After the first player on the team has thrown his firstball in the tenth frame, the rotation of cam 34I will cause cam contact34Ih to be first closed and then opened. By closing and opening contactscan, the stepper switch S5 will be energized and deenergized once onlythrough certain contacts hereinafter described to advance the wiper armsW of stepper switch S5 one step to contact point I0. If the first ballis a normal ball (not a strike or foul), S5 is energized throughcontacts 34Ih, 36Ib and Hill) (Figs. 8 and 9). If the first ball is astrike, S5 is energized through contacts 34Ih, 328a and 2y. If the firstball is a foul, S5 is energized through contacts 34m, 328a and M6).

The wiper arms W of stepper switch S5 will, therefore, be advanced tocontact point l0 regardless of whether the first ball is a normal ball,a strike or a foul. In case of a foul or a strike on the first ball, thesequence control shown and described in my copending application S. N.627,605 causes the machine to clear the alley and set up ten new pins.In case the first ball is a normal ball, the machine grips and lifts thepins which remain standing after the first ball is thrown above thealley to allow fallen pins to be swept off the alley, after which thelifted pins are replaced on the alley in the same position they occupiedbefore being lifted. Since the operation of the bowling machine andsequence control is described in detail in my copending application S.N. 627,605, further details of this operation if desired may be had byreferring to said application. 7

(c) SECOND BALL OF THE FIRST PLAYER IN 10th FRAME IS NOT A SPARE If thefirst player on a team throws his second ball, without committing anyfoul and without knocking down all of the pins, there will be some pinsstill standing on the alley. When the ball rolls into the pit, it willactuate the pit switch 300 (Fig. 8) of the sequence control described inmy copending application S. N. 627,605. When the table descends, it willcause the relay 328 to be energized thereby opening the normally closedcontact 328a. As a result, stepper switch S5 can be energized onlythrough contacts 34m and 36Ib. The contact 36Ib opens briefly whilecontact 34m remains closed due to the relative timing of cams 3H and 354(shown in Fig. 4 of my copending application S. N. 627,605). Thisresults in a double impulse to the solenoid I35 of stepper switch S5causing wiper arms W to advance two steps to contact points II and I2.In passing contact II, the wiper arm W of bank I of stepper switch S5causes relay I69 to be briefly energized but this has no effect in thiscase. In this case the sequence control, being in its second ballposition, cleared the alley and set up a new set of pins in the usualway described in my copending application, S. N. 627,605.

(d) SECOND BALL OF FIRST PLAYER IN 10th FRAME IS A SPARE If the firstplayer should knock down all the pins with his second ball (spare)without committing a foul, relay 328 will not be energized when therespotting table descends, as fully described in my copendingapplication S. N. 627,605 and, as a result, nor-mally closed contact32-8e will remain closed. The wiper arms W of stepper switch S5 will beadvanced one step to position 11 as a result of cam contact 34111. beingclosed by cam 34I, through contacts Mile and 4I2g.

This will allow the player one additional ball because he made a sparewith his second ball. He rolls this additional ball, which is his lastball, immediately.

Since the switch-over relay I6! is energized, contact I6Id is closed,thus transmitting current through contact point II of bank I of stepperswitch S5 to the relay I 69 thereby energizing the same. By energizingclearing relay I69, contact I69b will be closed thereby causing ratchetrelay 350 through wire I9I to operate during the operation of the=machine afterthe=player has thrown-. the additional ballhe wasallowed asa. result of making a spare in the lothframe. Whenthe' ratchet relay350-is forced to operate in this-mannen-itwill put the machine throughastrike'cycle,regardless of whether a strike is or is not made :with theadditional ball. A strike cycle causes the bowling machine to-clear thealley and set up ten new pins for the next player. During this cycle camcontact 34th will be closed and reopened by the rotation of cam 34!thereby energizing anddeen'ergizing solenoid I35 of stepper 'switchS5-and causing the wiper arms W of this switch-to advance to step 12.

-It will be noted that contact l 69a is connected inparallel withcontact 36lb through wires I8! and I89 and therefore no double impulseis transmitted :to stepper switch S5 by normally closed contact 36lbwhen the table turning relay 36! isactuated. If the player does notmakea strike withthis' additional ball, the strike lamp relay 368 =isnot energized when ratchet rela sfit is energized because no pin relaycontact 32823 is opened. If this ball is a strike the machine goesthrough its normal strike cycle, as described in my copendingapplication S. N. 627,605.

('6) FIRST BALL OF FIRST PLAYER IN th FRAME IS A STRIKE "If the'firstball of the first player in the 10th frame was a'strike, the wiper armsW of the stepper switch S5 advance from contact position 9 to'c'ontactposition 10 as previously described, and. the sequence control describedin my copending application S. N. 627,605 will be in first ball positionafter the machine has cleared the alleyand set up a new set of pins. Asa result of making astrike in the tenth frame, the first player isentitled to two additional balls which he throws immediately.

" After the first player has thrown his first additional ball, the wiperarms W of stepper switch S5 will advance only one step from contactpoint IO'to H for thesame reasons stated'in connection with the firstball'of the tenth frame regardless o'f'iwhether this ball is a partialhit, no hit, a strike or a foul.

Since wiperarm W'of bank I of stepper switch S5'is in'position ll,'relayI69 will be energized through 161d since the switch-over relay Isl isenergized.

"If the first player makes a strike with his first additional ball, thesequence control described in my copending application will causethemachine to clear the alley and set up a new set of pins. The electricalcontrol cams in my copending application would then be in first ballposition.

In thiscase, where the sequence control is in first ball position themachine is put through a strike "cycle after the second additional ballhas been thrown by the first player (this 'is the last ball to which heis entitled). Relay I69 being energized, has closed the contact l69b.After the second additional ball has been thrown relay 350 will beactuated during the operation of the machine and cause it to go throughastrike cycle. The stepper switch S5 advances the wiper arms W oneadditional step to position 12 becausecontact point I69a is closed as aresult of relay I69 being energized.

If the first player throws a no-hit, a partial hit, or'a foul with hisfirst additional ball, the electrical control cams of the, sequencecontrol described in my copending application referred to 14.- above"will be in secondball position asa-r'e'sult of the first "additionalball 'beingthrown. In this case, stepper switch S5 will only. advanceone more step to contact point 12 on account of [69d being closed. Sincethe machine is in sec- O-Ild ball position, the alley is cleared after.the second ball has been thrown and a new set of pins placed on thealley in the mannerfully described in my copending application S. N.627,605.

(fl FIRSTBALL OIEFIRST PLAYER IN 10th FRAME IS A FOUL In the events.foul'is made on the first ball in the tenth frame, S5 will be energizedthrough contacts MM, and 3286 and M67 thereby advancing the wiper arms Wof stepper switch S5 from contact position 9 to contact position 10 aspreviously mentioned. The operation of the foul circuit in this case isthe same as for-any first ball foul as described in my sequence .controlcopendingapplication Serial No. 627,6 5, namely H2, H6 and M8 operate insequence to set up ten new pins and advance the control to second ballposition at the .end of the foul cycle through double operation ofratchet-relay 356.

If the second. ball is not a spare or is afoul, the player will not beentitled to any additional balls, and the alley will be cleared and tennew pins set up in the manner described in my copending applicationSerial No; 627,605. The wiper arms W of stepper switch S5 will be movedfrom position 10 to position 12 by a double impulse to stepper witch S5due to the relative timing-of cams 3d! and 35 3 as previously mentioned.When the second ball is a foul, relay M2 is energized to light the foullight.

In the event the first player made a strike on his first ball, in thetenth frame, he would be entitled to two additional balls which he wouldroll immediately. If he makes a foul on his first additional ball, thesequence control will be operated in the same manner as in the case of afoul on the first ball in the tenth frame described above. In this casethe electrical control cams of the sequence control describedincopending application Serial No. 627,605 would go into second ballposition. When the player makes a foul with his second additional ballafter having made a strike in the tenth frame and a foul with hisfirstadditional ball, the machine, since it is in second ballpositiomoperates the'same as on the throwing of any other second ball.The alley is cleared and a new set of pins is placed on the alley andthe electrical I control cams of my copending application Serial No.627,605 go into first ball position. The foul relay H2 in this casewould also be energized to light the foul light.

Where the first player makes a foul on his second additional-ball, afterhaving made a strike with his first ball in the tenth frame and a strikewith his first additional ball, the operation of relay 416 (andconsequently M8) is prevented by the opening of normally closed contacti69c and the sequence control is prevented from shifting to second ballposition.

As shown in my U. S. Patent 2,559,274, in case of a first-ball strike,relay 2 is energized first, connecting the magnet of relay 416 inmultiple with the magnet of relay 356 through contact M20. Thus, whenrelay 356 is energized, relay llfi will also be energized. By insertingcontact I690 in series with contact M20, this connection is broken andthe operation of relay M6 is prevented on the last ball of a player.

(9) SECOND BALL IN 10th FRAME OF FIRST PLAYER CAUSES STANDING PINS TOMOVE FAR OFF CENTER If the first players second ball in the tenth framecauses a standing pin to move far off center so that relay 366 does notoperate, relay 328 is operated nevertheless through normally closedcontact 366d and locks in through holding contact 328d neither of whichcontacts was shown in my copending application Serial No. 627,605. Thiscauses contact 328e to open thus causing stepper switch S to advancewiper blades W two steps because the player did not make a space andtherefore is not entitled to any additional balls.

If the player makes a spare in the tenth frame thus entitling him to oneadditional ball or if the player makes a strike in the tenth frame and astrike with his first additional ball, the electrical control camsdescribed in my copending application Serial No. 627,605 will be infirst ball position when the player throws the last ball to which he isentitled. If this last ball causes a standing pin to move far oficenter, the closing of contact I691) causes relay 350 to operate eventhough contact 36511 is open. The opening of contact 16901 prevents theoperation of relay 400 which would otherwise operate to disengage thesweep so that all pins will be swept off the alley and ten new pinsreset. In this case the wiper arm W of stepper switch S5 would be inposition 11, and after the player has thrown his last ball, the wiperarms W of stepper switch S5 would be advanced from position 11 toposition 12 in the manner previously described.

(h) SECOND PLAYER, THIRD PLAYER, ETC.

After the first player has thrown his last ball, wiper arms W of stepperswitch S5 will have been advanced to step 12 as described above, whilethe wiper arms W of stepper switch S6 will remain on step 3. The samethree-count sequence is repeated for the next player on steps 12, 13 and14 of stepper switch S5 and for the third player on steps 15, 16 and 17of stepper switch S5.

Since we have assumed that there were three players on each team, in thecase used as an illustration, after the third player has rolled his lastball, the wiper arms W of stepper switch S5 advance to the step 18 whencontact sun is opened. The solenoid 135 of stepper switch S5 will thenbe connected to power through its interrupter contact I39, contact lBle,steps 18 to 23 on bank IV and contacts 4 and 5 on selector switch 54.This causes the wiper arms W of stepper switch S5 to spin on to step 24.When the wiper arm W of bank III of stepper switch S5 reaches step 24,it will energize the solenoid I3! of stepper switch S6 causing the wiperarms W of stepper switch S6 to advance to contact position No. 4. Thesolenoid I31 of stepper switch S6 is then connected to power throughinterrupter contact I41, contacts 4 and 5 on bank I of stepper switch S6and through contacts 4 and 5 on selector switch 54. Being energizedthrough its own interruptor contact Ml, stepper switch S6 will spin fromposition 4 till the wiper arm of bank I finds a contact without power,which is position 6.

At this point, relay l5! and the coin wheel locking magnet S! arereleased, thus reclosing contact I610 and applying power to contacts9-24 of bank II of stepper switch S5 and returning the wiper arms W ofstepper switch S5 to 16 zero position. Steps 6 to 23 on bank I ofstepper switch S6 are connected to power through wire I93 at the end ofthe final cycle of the machine by the reclosing of cam contact 36222(shown in Fig. 4 of my copending application S. N. 627605) .1

Stepper switch S6 advances from position 6 to position 24 by spinningsince contact points 6 to 23 of bank I of stepper switch S6 areenergized from cam contact 3621) referred to above.

At this point, the coin control clutch release magnet S8 (Figs. 1 and 9)is energized through step 24 on bank III of stepper switch S6 and thesolenoid i3! of stepper switch S6 is energized through contact point 24on bank IV of stepper switch S6. Selector switch 54 is returned to itsoriginal position by the clock spring 86 (Fig. 1).

The circuit between points 6 and I on selector switch 54 is broken andmotor control MC (Fig. 8) is deenergized and stops the motor. Switch Mopens, disconnecting power from the sequence control and solenoid I31 ofstepper switch S6 is deenergized and the wiper arms W of stepper switchS6 advance to zero position.

(i) CANCELLATION OF FOUL IMPULSE In this application, I have providedfor an automatic cancellation of a foul impulse in the event that aplayer steps over a foul line but does not throw his ball and therebyavoids what would have been a foul had be thrown the ball.

I have now provided a normally open contact 3081) instead of the formercontact 4l2b shown in Fig. 4 of my copending application S. N. 627,605,new U. S. Patent 2,559,274. The foul indicator is constructed with atiming device so that after a foul has been made, the relay magnet 469maintains the contact M6 in closed position for a predetermined lengthof time (for example about ten seconds) sumcient for even a slow ball toreach the pit. As long as the con tact 4!!) remains closed, relay 4l2will be energized through normally closed cam contact 3625 (Fig. 4 ofcopending application S. N. 627,605, now U. S. Patent 2,559,274) If theball reaches the pit within this predetermined period, the machine willstart immediately as described in my previous application and relay 4l2will be held in by the closing of contact 3538b until cam a I 4 opens(see Figure 4 of U. s. Patent 2,559,270;

If the foul impulse is not followed by a ball, foul indicator contact4l6 opens at the end of the above ten second delaying period therebyreleasing relay 4E2.

It is also possible to modify the sequence control shown in my formerapplication S. N. 627,605 by introducing a normally open contact onrelay 362 in the wire 4 in series with contact 416 of the foulindicator. The latter again must be of such a construction as to remainclosed for a limited period of time. In that case relay 4l2 will not beenergized until the ball reaches the pit and if no ball is rolledcontact 410 would reopen. This latter alternative does not have theadvantage of my first method in that there is no visual indication thata false foul has been committed and a player, therefore, would not have.any visual indication that it is all right to roll again.

The invention above described may be varied in construction within thescope of the claims, for the particular device selected to illustratethe invention is but one of many possible embodiments of the same. Theinvention, therefore, is not to be restricted to the precise details ofthe structure shown and described.
